High wind, blowing snow and low temps for Calgary today

UPDATE: well, THAT escalated.

Calgary's presently (as of 3:15) under a blowing snow advisory:

Since this system's being a bit of a pain, that's a blowing snow advisory for #Calgary.
"Blowing snow advisories are issued when winds are expected to create blowing snow giving poor visibility to 800 metres or less for at least 3 hours."#abstorm https://t.co/RVHTqLP9v2

The whole band, from the disturbance to the temperature drop to the end of the snow, started about two hours ahead of expectations, as this cold air rapidly swept in.

Our overnight temperatures will likely hold to the below-mentioned wind chills. That's more in the -30 C range.

PREVIOUS CONTENT: This rash of below-seasonal conditions will continue through the five-day, punctuated by periods of snow. If we have to pick a day that would be considered 'worse', perhaps, than the others, we’ll let that fall into tomorrow, where a wave of arctic air is shoving into us. That will bring snow showers (one to two centimetres), accompanied by gusts into the 50 km/h range. Factoring in our base temperature, the expected wind chill values could get awful close to -30 C late this afternoon.

This wave of cool air is an arctic high. Its cool air will clear cloud away for a day, but it remains chilly Friday; an early look at warmer air Saturday is in the forecast, guided over the Rockies by west wind, but that’s a one-day event. We’ll fall back into the previous pattern thereafter, and our high temperatures will dip into the negative double-digits once again, with more snow showers on the way to round out the weekend.

UPDATE: Temperature models, with very few exceptions, have adjusted to be even cooler for tomorrow and beyond. Except for Saturday. They're really optimistic about some warming Saturday. Tomorrow's snowfall will have few heavy moments, but will drastically limit visibility for evening commuters.
